An accumulator unit is a pressure vessel used in oil and gas well control systems to store the hydraulic energy required to operate a blowout preventer (BOP). This stored hydraulic pressure enables controlled closing of the BOP when required, with pressure capacity and configuration varying based on the type and operating requirements of the BOP.
BOP Accumulator Units
BOP accumulator units are critical components of well control equipment used to store and deliver the hydraulic power required to operate blowout preventers. Also referred to as BOP closing units, these systems store hydraulic energy that is released as needed to open and close BOPs during drilling and well intervention operations. Accumulator units also help stabilize hydraulic systems by providing pressure support during fluctuations commonly associated with positive displacement pump operation.
Designed for use across drilling rigs and well control applications, MEYER BOP accumulator units are engineered with serviceability and reliability in mind. Modular designs allow for future expansion and configuration changes, while accessible bottles and bladders simplify inspection and maintenance. Each unit is sized and built in accordance with applicable API-16D guidelines and engineered to deliver consistent hydraulic performance in demanding field environments.
In addition to manufacturing, MEYER provides flexible options to support operational needs, including aftermarket support for BOP accumulator units and BOP accumulator unit rentals for short-term, long-term, and leasing applications. These services ensure continued system performance and availability across major oil and gas operations.
MEYER BOP closing units are manufactured with:
- 2" seamless manifolds used in BOP accumulator and well control systems, with no joints, threads, or welds to reduce leak potential, improve structural integrity, and allow easier replacement
- Steel battery boxes to provide protection from the elements and direct impact
- Belt-driven pump system (not chain or gearbox driven) to support reliable hydraulic operation of BOP closing units
- Integrated lifting frame that protects the unit from damage and allows safe crane lifting during installation and transport
- Heavy duty 8" channel skid with forklift pockets for safe and easy lifting
- Gauge panels provide protection and allows for clear labeling
- Visible labeling showing operating positions, as well as, operational and safety notes
- 1" piping with crow’s foot connections designed to minimize air intake restrictions within BOP hydraulic systems
- High-Low Bypass
